Low Power 5V 1,000kbps RS232 Transceivers
General Description
Features
The ZT232F series devices are +5V powered EIA/TIA-232 and
CCITT V.28/V.24 communication interfaces with low power re-
quirements. These transceivers consist of two line drivers, two
line receivers and the proprietary switch-capacitor regulated
voltage converters. The ZT310F and ZT312F feature a low power
shutdown mode which draws as little current as 1μA typical with
receiver outputs tri-stated and in wake-up. These devices operate
from a single +5V power supply at the guaranteed high data rate
of 1,000k bits/sec with enhanced electrostatic discharge (ESD)
protection in all RS232 I/O pins exceeding 15kV ꢀHB.

Absolute Baximum Ratings
Storage Considerations
These are stress ratings only and functional operation of the
device at these ratings or any other above those indicated in the
operation sections of the specifications is not implied. Exposure
to absolute maximum rating conditions for extended periods of
time may affect reliability.
Storage in a low humidity environment is preferred. Large
high density plastic packages are moisture sensitive and
should be stored in Dry Vapor Barrier Bags. Prior to usage,
the parts should remain bagged and stored below 40°C and
60%RH. If the parts are removed from the bag, they should
be used within 168 hours or stored in an environment at or
below 20%RH. If the above conditions cannot be followed,
the parts should be baked for 12 hours at 125°C in order to
remove moisture prior to soldering. Zywyn ships product in
Dry Vapor Barrier Bags with a humidity indicator card and
desiccant pack. The humidity indicator should be below
30%RH. The MSL of this product is 3.

Proprietary Switch-Capacitor Regulated Voltage Con-
verter
effect the serial port and even subject it to transients that could
potentially damage the transceiver itself.
Different from other suppliers, Zywyn uses a patent pending
switch-capacitorvoltage-controlledsourceandsinkcurrentgen-
erators design to provide powerful bipolar voltages to maintain
compliant EIA/RS232 levels regardless of power supply fluctua-
tions.Thedesignconsistsofaninternalregulatedoscillator,atwo
phase clock cycling, regulated complementary BOS switches,
fast switching diode and switch capacitors.
The RS232 transceiver is usually routed from the serial port
connector to the transceiver IC through the metal trace on the
printed circuit board. This trace will have some small amount
of resistance that will add some protection in terms of limiting
transient current to the IC. ꢀowever for added voltage protec-
tion, transient voltage suppressors (TVS) or transzorbs, which
are back-to-back diode arrays clamp, are usually necessary to
protect the serial port circuity.
The switch capacitor bi-directional current generators operate
withZywyn’sproprietarysmartlyregulatedcomplementaryBOS
switchesandfastswitchingdiodefromitsproprietaryhighvoltage
processtechnology.Theefficiencyofthesebi-directionalcurrent
generatorsiswellover70ꢁ.Theswitchingfrequencyisgenerated
by an internal oscillator and regulated by the current loads. The
switch capacitor pump design delivers higher negative bucked
voltage than the positive boosted voltage to achieve a balanced
voltage controlled source and sink current generators resulting
a balanced bipolar voltage supplies to the chip.
To further reduce cost within their system, more engineers are
requiring higher ESD tolerances from the transceiver ICs them-
selves without having to add costlyTVS circuitry. Zywyn's RS232
transceiversincludesbuilt-intransientvoltagesuppressionwhere
external ESD circuitry is not necessary to meet the BIL-STD-883,
Bethod3015,ꢀumanHodyBodelandtheEN61000-4-2Air/Con-
tact Discharge tests.
The ꢀuman Hody Bodel has been the generally accepted ESD
testing method for semiconductors. This test is intended to
simulatethehumanbody’spotentialtostoreelectrostaticenergy
and discharge it to an integrated circuit upon close proximity or
contact. This method will test the IC’s capability to withstand an
ESD transient during normal handling such as in manufacturing
areas where the ICs tend to be handled frequently.
With its unique proprietary design technique, Zywyn’s interface
productseriesprovideabetterpowerefficient,stableandcompli-
ant EIA/RS232 levels with superior low power consumption.
Controlled Enable and Power-Down
EN61000-4-2 is used for testing ESD on equipment and systems.
Forsystemmanufacturers,theymustguaranteeacertainamount
ofESDprotectionsincethesystemitselfisexposedtotheoutside
environment and human presence. EN61000-4-2 specifies that
the system is required to withstand an amount of static electric-
ity when ESD is applied to exposed metal points and surfaces of
the equipment that are accessible to personnel during normal
usage. The transceiver IC receives most of the ESD current when
the ESD source is applied to the connector pins.
The ZT310F and ZT312F both feature an enable input, which
allows the receiver outputs to be either tri–stated or enabled.
This can be especially useful when the receiver is tied directly to
amicroprocessordatabus. FortheZT310F, enableisactivelow, in
whichalogicꢀIGꢀ appliedtotheOFFpinwillenablethereceiver
outputs. For the ZT310F, enable is active high in which a logic
ꢀIGꢀ applied to the EN pin will enable the receiver outputs.
ZT310FandZT312Fhavealow-powershutdownmodecontrolled
by the ON/OFF pin for the ZT310F and the SꢀDN pin for the
ZT312F. During shutdown the driver output and the switch-ca-
pacitor regulated voltage converter are disabled with the supply
current falls to less than 1μA.
There are two methods within EN61000-4-2, the Air Discharge
method and the Contact Discharge method. With the Air Dis-
charge Bethod, an ESD voltage is applied to the equipment
under test through air, which simulates an electrically charged
person ready to connect a cable onto the rear of the system and
the high energy potential on the person discharges through an
arcing path to the rear panel of the system before he or she even
touches the system. The Contact Discharge Bethod applies the
ESDcurrentdirectlytotheEUT.Thismethodwasdevisedtoreduce
the unpredictability of the ESD arc. The discharge current rise
time is constant since the energy is directly transferred without
the air-gap arc inconsistencies.
ZT312F includes a wakeup function that enables both receivers
during a shutdown state. With only the receivers active during
the shutdown state, the devices draw 5-10μA of supply current.
A typical application is when a RS232 cable is connected or when
the peripheral is enabled such as a modem, the devices will au-
tomatically become active again. After the supply voltage to the
ZT312F reaches +5.0V, the SꢀDN pin can be disabled, taking the
ZT312F out of the shutdown mode. All receivers that are active
during shutdown maintain 500mV (typ.) of hysteresis.

RS232 Signal Characteristics
The charge pump voltage converter efficiently converts the
necessary voltage for the driver's output transistors so that the
RS232 output is close to the ideal rail voltage of 10V.
ThereceiversconvertRS-232inputsignalstoinvertedTTLsignals.
The inputs have a typical hysteresis margin of 500mV in order
to account for signal degradation caused by system interfer-
ence and other noise related disturbers. This ensures that the
receiver is relatively immune to noisy transmission lines. The
input thresholds are 0.8V minimum and 2.4V maximum, which
are within the TIA/EIA-232 requirements. The receiver inputs are
also protected against voltages up to 25V. Should an input be
leftunconnected,a5kohmpulldownresistortogroundwillforce
the output of the receiver to a high state.
While loaded with a typical RS232 load, the driver's output level
only drops 0.2V from its open circuit voltage. Zywyn's low-drop
driver circuitry working with its efficient voltage regulator allows
superior line driving capability while meeting the requirements
of TIA/EIA-232-E.
The drivers are inverting transmitters, which acceptTTL or CBOS
inputsandproducestheRS-232compliantsignalsthatisinverted
relativetotheinputlogiclevels.TypicallytheRS232outputvoltage
swing is 6V. Even under the worst case loading conditions of
3kohms and 2500pF, the output is guaranteed to be 5V, which
adheres to the RS232 standard specifications. The transmitter
outputs are protected against infinite short-circuits to ground
without degradation in reliability. The instantaneous slew rate
of the transmitter output is internally limited to a maximum of
30V/μs in order to meet the TIA/EIA-232-E requirements.
